Title: Improvements in the separation of hydrogen chloride from mixtures containing olefines or diolefines
IPC: C01B7/07
Filed: 1938-08-31
Abstract: 518,745. Distilling hydrocarbons. JOHNSON, G. W. (I.G. Farbenindustrie Akt.-Ges.). Aug. 31, 1938, No. 25498. [Class 32] [Also in Group IV] Hydrogen chloride is separated from mixtures of it with olefines and diolefines by bringing the mixture into contact with a liquid which is inert to hydrogen chloride and has a boiling point higher than hydrogen chloride but lower than the olefines. Suitable inert liquids are propane, propylene, methyl chloride, vinyl chloride, and dichlorodifluomethane. According to an example, a mixture derived from the thermal splitting of dichlorbutane and consisting of hydrogen chloride and butadiene with some propylene and butylene is introduced at room temperature into the column 2 and liquid propane at -45‹C. is injected at 3. The butadiene is liquefied and collects in the bottom of the apparatus where the temperature is such that it boils slightly. The vaporized propane and the hydrogen chloride are led off at 4, compressed at 7, cooled at 8, and separated in the still 10 from which the propane is recirculated. The butylene is also condensed with the butadiene and the propylene. escapes with the vapour.

Abstract: 749,918. Copy-turning; lathe details. WERNER, H., and WERNER, H. H., [trading as WOHLENBERG KOMM.-GES., H.]. Sept .15, 1953 [Sept. 15, 1952], No. 25513/53. Class 83 (3). A lathe has a tracer-controlled profiling slide 43, Fig. 2, disposed behind the work-spindle axis and formed with guide-ways 45 on which a tool-holder 58 is mounted for adjustment, relative to slide 43, towards and away from the work, by a manually-operated shaft 36 journalled in and disposed at the front of the saddle 11 which carries a cross-slide 13 supporting a swivel plate 18 having guideways 46, Fig. 1, for the slide 43. Two threaded shafts 15, 17 lying side-by-side and a splined shaft 16 are journalled in the saddle, which carries a further cross-slide 14 supporting a swivel-plate 19 on which is mounted a tool slide 21 disposed in front of the work-spindle axis. Shaft 15 engages a nut 63 fixed to slide 13 and shaft 17 engages a nut 94 fixed to slide 14 whereby slides 13 and 14 may be fed. Shaft 16 engages a bevel gear 78 fixed to slide 13 and drives, via gears 77, 76, 75, 72, 73, 74, a splined shaft 69 journalled in swivel-plate 18. Gear 68 engaging the shaft and carried by slide 43 for movement therewith, drives worm wheel 67 and pinion 65 meshing with a rack 64 on the tool-holder 58. Thus, rotation of shaft 16 causes movement of holder 58 relatively to slide 43. Shaft 16 also engages a bevel-gear 31 fixed to slide 14 and driving via gears 30, 29, 28, 26 a bevel-gear 25 connectable through manually-operable clutch 24 to a threaded shaft 22 journalled in swivelplate 19 and engaging a nut 23 fixed to slide 21. A sleeve 33 is rotatable on shaft 16 and has teeth 32 driven by the lathe feed-mechanism. A toothed sleeve 94<SP>1</SP> keyed to shaft 17 is movable by yoke 93 to engage teeth 35 on sleeve 33 whereby power-feed may be applied to shaft 17. A toothed sleeve 37 keyed to shaft 36, which is co-axial with shaft 15, is movable by a yoke 38, (a) to the position shown in which dogs 62 engage shaft 15, (b) to engage teeth 35 and a pinion 34 fixed to shaft 16 or (c) to engage pinion 34 only. Thus shaft 15 and shaft 16 may be power-fed or shaft 16 may be rotated by fitting a hand crank to squared end 42 of shaft 36 The yokes 93, 38 are moved by threaded shafts 92, 39, respectively, having handles 91 and 40. Shafts 15, 17 may be manually fed by-applying hand cranks to their rear ends. Gears 72, 73 are disengageable to allow of adjustment of slide 21 without moving tool-holder 58. Specifications 749,205 and 749,917 are referred to.

Abstract: 204,889. Smith, J. Sept. 28, 1922. Rope grips.-Comprises a cam-actuated grip with quick-release mechanism. Movement of the lever G towards the right rotates the shaft C and cam B to admit of the insertion of the rope. On release, the lever drops by gravity and jams the rope between the upper surface of the cam and the head of the casing. If a second movement of the lever G towards the right fails to release the rope, a latch F is knocked upwards to free the block D. A blow on the projecting pin E then moves the block axially until the cam shaft C drops into the recesses in the upper side of the block and thus frees the rope.

Abstract: 1,075,451. Impulse diallers. GENERAL ELECTRIC CO. Ltd. July 19, 1965 [June 24, 1964], No. 26166/64. Heading H4K. In a repertory impulse dialler each digit of a multi-digit number is encoded in a row of a punched card which is sensed a row at a time as the card is pulled into the dialler upon successive operation of a pawl acting upon a toothed edge of the card; the position of the punched hole in a row causes a particular one of the contacts of a wiper-switch to be marked which determines the extent of angular movement of an electrically driven shaft carrying the wiper, the shaft on its return motion transmitting a number of impulses proportional to the extent of angular movement and hence indicative of the digit. The shaft carries cams which during the forward motion operate the pawl to introduce a new row to a set of contact rods carried on a pivoted plate which are then pressed against the card to sense the position of the hole and effect the marking and are withdrawn upon the return motion of the shaft. At the extreme limit of travel of the shaft, which it reaches when there are no digit holes to be sensed, such as at the end of the card, a wipered contact is permanently marked to reverse the motion of the shaft and two further cams cause the impulsing contacts to be then short circuited during the return motion and a relay to be operated to stop any further forward motion of the shaft and generally disable the dialler. This disabling relay can be over-ridden by a contact operated by a punched hole corresponding to a long interdigital pause. Use is made of this facility when the shaft is first rotated upon receiving the card but before the first row reaches the sensing location, by providing a hole in the I.D.P. position in the spring-biased plate against one edge of which the card is pulled. A magazine houses the punched cards and is driven electrically lengthwise to present the desired card at the sensing location by means of a marked contact of a set which is wiped during the lengthwise movement. The card is then partially extracted by a rod operated by a cam on the shaft so that a pawl and detent mechanism engage the first of a set of teeth along one edge of the card ready to further extract the card upon successive sensing of the digit rows. A latch mechanism locks the magazine in position during dialling which then releases to allow the magazine to be driven back to its home position. The digits may be encoded magnetically upon the card. The dialling may be made without lifting the handset and an additional loud-speaker informs the subscriber when connection has been made or otherwise. The connection may be automatically released if the handset is not lifted within a certain time.
